I am familiar with RTBezierLine (I mentioned it in the original question), but what I was wondering about was whether controllingElements: should be added to RTMultiLine (so it will be handled internally just like in BezierLine), or leave it as is and let the user handle it from outside - as demonstrated by the example I posted.
